IPC: B01D19/02
Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To efficiently defoam washing water without lowering the efficiency in recovering washing water by forming a defoamer for removing the bubble generated in a washing water recovery tank when the washing water for washing a work in a coating stage is recovered with a bubble collecting part, a defoaming chamber and a means for reducing the pressure in the defoaming chamber to burst the bubble. SOLUTION: When the water having washed a work 16 in a washing booth 14 is recovered, a large number of bubbles 24 are generated in a washing water recovery tank 12 and floated on the water surface. Accordingly, a bubble collecting nozzle 26 in a defoamer 10 is arranged out of contact with the water surface in the recovery tank 12, and the bubbles 24 are sucked and collected from the open end of the nozzle 26 by the air current generated due to the pressure difference between the recovery tank 12 and a defoaming chamber 30 provided with an exhaust fan 32 as a pressure reducing means. The collected bubbles 24 are introduced into the defoaming chamber 30 through a pipe 28, and the air current contg. the bubbles 24 is discharged along the curved inner wall face of the chamber 30 and revolved.  The defoaming chamber 30 is then depressurized, and hence the bubbles 24 are expanded, burst and broken.

Title: Etching mask
Inventor: MURATA SHIGERU
IPC: H01S5/00
Filed: 1985-10-04
Abstract: PURPOSE:To provide an etching mask for manufacture of BH lasers in which a desired width of an active layer can be obtained with good reproducibility, by forming the mask of an InGaAs layer having an energy gap smaller than or equal to that of the active layer. CONSTITUTION:An InP buffer layer 102, an InGaAsP active layer 103, an InP clad layer 104 and an InGaAsP mask layer 105 are grown on an InP substrate 101 with (001) face orientation, sequentially in that order. The mask layer 105 has an energy gap Em smaller than or equal to the energy gap Ea of the active layer 103 and has a thickness approximately equal to that of the layer 103. If Em is larger than Ea, the active layer 103 is etched more rapidly than the mask layer 105 and the width of the active region included in a mesa section 122 from which the mask layer 105 is to be completely removed is reduced by side etching. For this reason, the mask layer 105 must be selected such that Em is smaller than or equal to Ea.
